TQ all whom z't may concern:

Be it known that I, ERNEST zen of the United States, and a resident ofthe city of New York, Dongan Hills, borough of Richmond, in the countyof Richmond and State of New York, have invented a new and improvedMetal Window, of which the following is a full, clear, and exactdescription. f

My invention relates to metal windows, and the object thereof is toprovide asimple, inexpensive and reproof window which will give a largerlight opening than the ordinary metal windows by decreasing the size ofthe window frame and fitting the window sashes over the frame; andwhich' window structure is weatherproof.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the inventionconsists in thenovel construction, combination and arrangement of parts as herem fullydescribed, illustrated and claimed. 1n

the accompanying drawings, forming part of the application, similarcharacters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section through my window; y

Fig. 2 is a cross section on line 2-2 through a jamb and sashes of thewindow;

Fig. 3 is a fragmentary perspective view of the sill in section; and

Fig. 4 is a vertical section of a modified structure of my window.

Referring to the drawings, 5 is the window sill formed of metal andpresenting a raised step 6 at the rear. It has a downwardly-directedHange 7 at the outer edge of the sill, and a downwardly-directed flange8 at the inner edge of the sill in the rear of the step. The front edgeof the step 6 overhangs the inclined surface of the sill to form thereata groove or channel 5. Vertical, corner-iron-shaped projections 9 areprovided at each end of the sill, the inward walls of said projectionsfacing each other, the other walls of the projections being located atthe outer edge of the sill and pointing in the opposite direction.Against each projection the lower end of a corneriron-shaped jamb 10 issecured. The lintel 11 of the frame is also, preferably, inthe shape ofa corner iron.

A pair of spaced, channeled strips 12 are secured to each j amb with thebottom of the channel lying against the'jamb. The facing channels on theopposite j ambs form guides for a sash 13 of the window. The stiles 14:and railsv 15 of the sashes have flanges at the edges which are thesides of channeled iron forming the sash, the channeled stiles of thesashes receiving the sides of the corresponding channeled strips and areguided thereby. It will be noted that the distance between the strips 12isv such as to admit therebetween the adjacent sides of the channeledStiles. Due to the engagement of the stilesvwith the strips, stop stripsare' unnecessary. The lsinuous joint formed' by each stile with thecorresponding strip makes the connection between the sashes and theframe weatherproof. vTo render weatherbead formed by the anges 19extending from the bottom of the channeled Stiles and rails in adirection opposite to their sides. Each of the sashes is suspended froma sash balance 20 mountedon the lintel 11 and connected to thecorresponding sash by a Iribbon 21 which extends within a correspondingchanneled strip 12.

ln the modified structure shown in Fig. 4, the rails 22 and the stiles23 of the sashes 13 are formed of 1.shaped irons; consequently, a stop24 is` provided to lock the lower sash to the channel-shaped strips 12.

The upper sash is locked to its channeled strips 12 by the innerchanneled strips.- 1t will be noted that to remove the sashes in thestructure disclosed in Figs. 1 to 3 inclusive, it is only necessary todetach the channeled strips 12 from the jambs and the sashes can betaken out. In the structure shown in Fig. 4:, to remove the sashes thestop 24 must first be removed, thusleaving free the lower sash 13 Byremoving the inner strips 12 the upper sash can be removed. By makingthe engagement of the channeled strip with the channeled Stiles thelight opening within the frame is increased without increase of thewindow frame, and due to the sinuous joints formed between the channelsinthe sashes and the 'f guidec iron, the inner walls of said projectionsfacing, the \other walls being located at the "outer sill edge andpointed in the opposite direction, a corner-iron-shaped ]a'mb risingfrom the sill at each projection, 'a lintel uniting the jambs, a pair ofspaced channeled strips secured to eachA j amb so that the bottom of thechannel rests on the jamb, a sash rail of the lower sash beingadapted\t0 receive the step of the sill, and a channeled strip on thelintel to be received by the upper channeled rail of the upper sash.

In testimony whereof` I have signed my' name to this speciication in thepresence of two subscribing witnesses.
